Discuss Nanci's answer to: Pet Friendly Concentrated Ceramic Floor cleaner?

Good old white vinegar and water....Ü   they may not like the smell, but it won't hurt them.  If you are looking for a grout cleaner?  Make a paste of baking soda and peroxide....let it sit on the grout for half an hour or so, and scrub it with a toothbrush, then wipe it down well, and mop everything back down with hot water (that you can also throw a splash of vinegar into.)   For grout that is darker, (depending on the grout, peroxide may bleach it out lighter)...oxy-clean from the dollar store made into the same paste also worked really well for cleaning, and I have not personally had any trouble with my cats, but have not investigated into specifics regarding animal safety.
